Measuring command response times using ptime

Measuring command response times using ptime

 Every time I write about automated testing, batch files and measuring performance, I get quite a bit of emails asking for more details, more tools or if I can help.

One request I get regularly is people asking if I knew of a tool that will measure the time it takes a command to complete a task. Took me a while scouring the internet and testing a bunch of tools.

Modelling Microbursts and Packet Queues What is a primary cause of slow throughput in today’s wide-bandwidth networks?


Packet loss

How just a few packet losses can have a debilitating effect on throughput is another matter and has been very well studied –


This takes us into the fields of TCP flow control and congestion avoidance.

What you didn't know about DDoS attacks (Tom Bienkowski )

 Even before the current pandemic, the types and velocity of distributed denial of service (DDoS) attacks were on the rise!

And with the architectural changes brought about by COVID-19—such as greater reliance on VPN gateways as more employees work from home—organizations are at increased risk of disruption. In fact, according to NETSCOUT most recent Threat Intelligence Report, we have seen a 15 percent increase in DDoS attacks in 2020 compared to the same period in 2019—and a 25 percent increase over the height of the pandemic lockdown. At present, we are on track to experience more than 9 million attacks this year.

Sentient Stuff (Paul Smith)

Those of us who have worked in the data storage industry often wonder how our computers match up to the processor we carry around in our own heads. Comparisons are difficult to come by – we can estimate the average number of neurons in a human brain (~ 86 billion), but they are quite different from the “bits” that comprise computer memory. If they functioned in the same binary way, we would have the storage equivalent of a typical flash drive, and we’d have to start deleting less important memories by the time we reached sixth grade.
